The only reason to install an electric pump is that you have something else wrong that needs attention. And the only pump in the system is the injection pump. You can’t bypass that, if you want it to run.
Why don’t we start with some troubleshooting?

Bought the truck awhile back and have replace all the normal maintenance stuff; fuel filter, oil, etc. I ended up losing a copper crush washer from the injection line to the banjo bolts. Finally found some new washers but then broke a banjo bolt. Ended up finding some bolts and went to put them on and it wouldn’t start. Put a new starter on it and now it cranks but isn’t getting any fuel..so that’s where I am, bought an electric pump and have everything ready to install. Excuse some of my wordage I’m not terribly mechanically inclined
Not a problem. Sounds like you're making some progress. It just occurred to me that you were referring to the priming pump. I didn't think of that because it's only used when you replace a fuel filter, run out of fuel, or otherwise open up the fuel system. Those primer pumps can go bad, but it's generally something else (easier and cheaper).
It is very normal to take a while to get it to "fire" once you've opened up the fuel system. I have no doubt you're right, it isn't getting any fuel. You can help speed it up by bleeding as much air as possible from the system. To do that, you need to find the line that runs from your priming pump to the fuel injection pump. Disconnect that from the injection pump. Begin pumping (pressing the disk on top of the primer) and continue until fuel dribbles out of the line you disconnected. The priming pump has a very short stroke, so don't assume it's not doing anything. If you get this far, report back here. I'll hold off on next steps, because you may not get fuel. That's a different issue we'll need to troubleshoot.
